SAW SET.

Application mea December 1s, 1922.Y seriai No. 607,590.

' 'To all wh-0m t 'may concern:

. whereby the punches carriedV thereby can be Be it known that I, JAMES L. ALLEN, a citizen of the United States, residing at Memphis, in the county of Shelby andState of Tennessee, have invented certain new and useful Improvements in Saw Sets, of which' theA following is a specification, reference being had therein to the accompanying drawing. i

This invention relates to certain new and useful improvements in saw sets'and more particularly to saw sets adapted for setting the teeth of circular saws, the object being to provide a set-in which the movement of the operating lever will set two teeth when moved in one direction and when moved in the reverse direction will move the saw in position to have the succeeding pair of teeth in position to be operated onby the punches for setting the teeth.

Another and further object Vof theinvention is to provide a' saw set which is eX- i ceedingly simple and cheapin construction, the parts being so arranged and connected together that they bled or taken apart.

A further object of the invention is to provide novel means for adjusting the movement of the setting punches for regulating the set ofthe teeth.

Another and still `further object of the invention'is to provide novel means for supcan be readily assem- `porting and adjusting the position of the sawin respect to the setting punches whereby saws 'of various sizes can be set.

A' still further object of the invention is to provide a saw set with adjustable anvils properly positioned in respect to theteeth of the saw regardless of the design thereby enabling the set to operate on all styles of saws. v Y

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereofdeined by the appended claims.

In the drawings,

Figure 1 is a side elevation of a saw set constructed in accordance with my invention;

Figure 2 is an inverted plan view;

Figure 3 is a section taken on line 3--3 of Figure 2; Y j

Figure 4 is a detail view of the saw supporting carriage showing the manner of supporting the saw; and

Figure 5 is an enlarged view showing the manner of operating the punches by the cams for setting the teeth of the saw.`

In the embodiment of my invention as Vherein shown, l employ an anvil frame formed of members 1 and 2 interlocked together by tongue and groove so as to form an adjustable frame which is secured in its adjusted position' by a bolt 3, the member 1 being provided with an extension t for securing the same to a bench yorsupport.

The inner walls of the members 1 and 2 are provided with `dove-tailed grooves 5 and 6 in which are slidably mounted dove-tailed tongues 7 and 8 of anvils 9 and 10 which are adjustably mounted 'and secured in their adjusted' position within said frame by set screws 11 and 12 as clearly shown in Figure 3, said anvils being spaced apart and adapted to'receive a saw as will be later'described. v

The anvils are provided with punches `13 and 4141C which extend outwardly through slots formed in the members 1 and 2, said punches being surrounded 'by springs 15 and with Va threaded nut through which extends,

a feed screw 22 adapted to be operated by a crank 23 so as to adjust the saw between the anvils. By providing adjustable means for Vsupporting the saw between the anvils, saws of various sizes can be positioned between the anvil forsetting the teeth thereof. The members 1 and 2 `forming the anvil frame are provided with stud bolts 24 and 25 on whichY are pivotally mounted the arms 26 and 27 of a lever frame, said lever frame being provided with a handle portion 28. By constructing the lever in this manner,v the arms 26 and 27 which are secured'together by a bolt 29 can be separated so as to allow the same to be placed in position upon the stud bolts 24`and 25 upon which the lever is pivotally mounted. i

Secured in a threaded opening() formed in the member 1 is a bifurcated stud bolt 31 inl which is pivotally mounted an arm 32 having slotted ends as clearly shown in Figi vils 9 and l()v by ure i. Mounted in one ofthewslotted ends of the aifi'n?d is a tooth-engaging member' 33 which is provided` with a hooked end adapted to extend between the teeth ot the saw.

Secured to the handle portion of the lever are a pair of links 34 connected together by a pin 35 which is slidably mounted inthe slotted end of the arm 82 so that when the lever is operated, the tooth-engaging meinber 33 .will ride over tlieteethfaiid when the lever is Operatedin the reverse direction,

the saw will be rotated so as to bring into position two additional teeth tobeoperated on by the punches 13 and 14.

The armsQ and 27 or' the lever are provided with cams 36 and 37 which areadapted toeiigage the ends or" the punches 13 and le so as to torce the punches inwardly against the tension ot' thespi'ings in order to set vthe teeth io'f the `saw when arranged between the anvils 9 and l0. in order to provide means i''or regulating the movement ot' the punches lso as to determine the set ot' the teeth, l rprovide the anvil 'trame with means for .limiting the swin `ing movement ofthe lever in the form .of acurved ,plate 38 provided withslotsin its endy which are mounted bolts 39 carrying stops 4 0 arranged in the path of travel ot the operatring lever andgit willbe seen thatby adjust-r ing these stops, the *niovenientv of the lever can be regulated soos toadjust'the movement of the punches.

The movable arriage l'S is locked iiiits adiusted position :titer the saw carried thereby liasbeen positioned between theanspindle carried the carriage is so conKK structed that the saw is held thereon in such inannerthat it can rotate in order to allow the teeth to be positioned between theanp vils to be operated on by the punches when the leveris moved'in one direction so as to bring-the cams into engagement with the iree ends ot thepunches. As the punches re moved inwardly, two of thev teeth of the sav-J ,are operatedpon simultaneously so as to net thesame. On the reverse movement ot the lever, the saw is rotated on thespindlc by thetooth-engaging feedingvmeans vso tobring two additional teeth in positionbe tween theanvils to be operated on by the punches and it will be seen that after the etscrews 4l and the `saw* exceedingly simple andcheapand one in which the f-:etting punches are operated by u movabielerer which also operates the Afceding' means tor rotating the saw to posi l tion the teeth in respect to the punch and have tound in practice that a saw set constructed in accordance with my invention vwillset the teeth ota saw very quickly and accurately.
